Urgh, it seems this machine gets the problem exactly at the one point
where I mistakenly used debug_printf, not system_printf for the detailed
output.  I've fixed that.  The next snapshot should at least print
some address and flag values.

How do you do this?  I added the shell functions you sent to my bash
.profile, but when I start bash under strace, it still never calls mmap.
